The Kerr-de Sitter spacetime in Bondi coordinates
arXiv:2108.01098 · doi:10.1088/1361-6382/ac2c1f
Abstract
We use zero angular momentum null geodesics in the Kerr-de Sitter spacetime to transform the metric in a generalised Bondi coordinate system. We write the metric components explicitly. Next, we choose the radial coordinate to be the areal coordinate and write the asymptotic metric in the Bondi-Sachs gauge.
